Age of Spirits: How to Beat Stage 150 Cavern Fiends

To clear Stage 150 in Age of Spirits, replace single-target attackers with wide-area flame damage dealers, disable automatic skill casting, and anchor a durable frontline tank in the middle of the cavern corridor. The encounter features tightly packed waves of cavern fiends that overwhelm squads relying on single-target focus. Waiting to fire flame barrages until the fiends funnel and compress against your frontline clears whole packs before their accumulated damage threatens your squad.

Squad Setup and Role Requirements

Stage 150 restricts lateral movement, funneling fiends directly toward your team. Pure single-target damage dealers waste valuable cooldowns on individual low-health targets while trailing fiends advance untouched. Build your warband around area-of-effect coverage and crowd control:

• Frontline Tank: Place a durable tank in the center of the lane ahead of the rest of the squad. This anchors the fiends in a narrow choke point and prevents them from wrapping around your flanks.
• Fire-Based Casters or Ranged Units: Fill your mid-line and backline with units capable of wide flame arcs, ground burns, or chain explosions. These skills ensure ability energy hits the entire cluster simultaneously.
• Defensive Support: Bring shielding or healing skills timed to deploy right as charging fiends collide with your frontline.

Battle Execution and Ability Timing

The narrow cavern path works in your favor if you control when skills trigger. Automatic skill deployment fires abilities at the first enemy that enters range, wasting major cooldowns on wave scouts. Manual control lets you group enemies for maximum damage.

Follow this rotation through each wave:

1. Let the enemies bunch up: Do not activate long-cooldown skills while enemies are still walking down the corridor. Allow the lead fiends to hit your tank, which forces the rear ranks to pack tightly behind them.
2. Apply defensive buffering: Cast your shield or heal right before the wave makes full impact to prevent your tank from taking unmitigated burst damage.
3. Trigger the flame barrage: Drop your primary area flame abilities directly over the gathered swarm. Overlapping fire skills eliminate the bulk of the pack in seconds.
4. Reserve energy on low-health targets: When only a few injured fiends remain, hold back high-cost skills. Kill them with basic attacks to enter the next wave with fully charged abilities.

Positioning Rules for Cavern Choke Points

Keep a distinct gap between your frontline tank and your rear-line flame casters. Packing your entire squad together allows sweeping fiend attacks to hit your damage dealers and interrupts their casting animations.

Placing your tank slightly forward in the central path holds the enemy wave at distance. If the front line gets pushed back momentarily, this buffer preserves clear line-of-sight so your ranged units can channel their barrages without interruption.
